Best PEO Services for Small Business (2026)
A PEO (Professional Employer Organisation) is the opposite of DIY HR software — instead of managing everything yourself, the PEO handles payroll, benefits, compliance, and risk management on your behalf. The trade-off is cost and control: PEOs are more expensive per employee than software-only solutions, but they do significantly more work and give small businesses access to benefits packages that would be impossible to negotiate alone.
The PEO model makes most sense for US companies with 5-200 employees that want enterprise-grade benefits without building an HR department. Justworks is the most transparent and tech-forward option. TriNet offers the deepest industry expertise. Gusto and Rippling sit between pure PEO and DIY software, offering some PEO-like features (benefits brokerage) without the co-employment model.

Frequently Asked Questions
What is a PEO?
A PEO (Professional Employer Organisation) is a company that co-employs your team. They take over payroll, benefits administration, workers' compensation, and regulatory compliance. You retain control of day-to-day management and hiring decisions. The co-employment model gives small businesses access to benefits packages normally available only to large employers.
How much does a PEO cost?
PEO pricing typically ranges from $59-$150 per employee per month. Justworks starts at $59/employee for basic payroll and compliance, rising to $109/employee with benefits. TriNet charges $80-$150/employee depending on services. Factor in that PEO benefits costs are often lower than what you'd pay independently.
PEO vs DIY HR software — which is better?
PEOs are better for small businesses (5-200 employees) that want HR outsourced and big-company benefits. DIY HR software (Gusto, Rippling, BambooHR) is better if you want control, lower costs, and are comfortable managing HR processes yourself. PEOs cost more per employee but do more of the work.
